Roos-CARLINE'.

Specification of Letters Patent.

. To all whom it may concern:

.turesof strength, lightness, and economy of construction, and present simple and effective means for connecting and firmly supporting the ridge pole and purlins in their respective positions in the roof structure, and for being supported on the' car side plates and acting as a tie between the-opposite sides of the car.

To this end, my invention, generally stated, consists in the combination of two compression members of angle section, bent downwardly from their middle the roof.

portions towards their ends, and a tension member or tie interposed between the compression members and connected theretoadjacent to its ends.

The improvement claimed is hereinafter ully set forth.

`In the accompanying drawings: Figure 1 is a side view, in elevation, showing slightly more than one half in length of a roof carline embodying my invention; Fig. 2, a plan or top view of the same; Fig. 3, a view, similar to'Fig. 1, showing a modification of structural detail; Fig; 4, a plan or top view of the roof carline of Fig. 3; Fig. 5,`a vertical central section through that of Figs. .l and 2; Fig. 6, a similar section through that of Figs. 3 and 4; and, Figs 7 and 8, similar sections illustrating modiied forms bf the tensionmember or tie.

In the practice of my invention, lf provide two compression members, l, of rolled or pressed metal, which are of angle section, as, for example, ordinary commercial shape angle bars, and are placed at a short distance apart, their horizontal portions being uppermost and turned outwardly from their vertical portions, and being in line one with the other throughout their length. The compression members, 1, are fiat at their middle portions, for a'distanceabout equal to'the width of the ridge pole, 4', of the car roof for which they are designed, and are thence downwardly bent or 1inclined towards ltheir ends, at and adjoining which they rest on the side plates, 2, of the car frame, at such' angle as may be adapted to impart the desired pitch As shown in Fig. l, the compression members are continuously inclined from each side of the central flat ridge pole bearing to the inner sides of the side-plates, while in Fig. 3, they are fiat for a'short distance adjacent to each side plate and inclined for` the remainder of the distancebetween the same and the ridge pole bearing.

A tension member or tie, la, which is preferably, as shown, straight or unbent throughout its length, is interposed between the two compression members, and is connected thereto, adjoining their-ends, by horiz ontal rivets or bolts, 6. As shown in Figs. l, 3*, 5, and 6, the tension member is a flat bar, set vertically or on edge, but it may, ifpreferred, be made of different section, as for example, a T bar, as shown in Fig.

f7, or a plate of greater depth at its middle portion than at its ends, as' shown in Fig. 8.

The compression members 1, are secured to the side plate, 2, by vertical bolts, 3, and the -tension member, l, vis preferably vturned laterally into end flanges, ld, which abut against the outer sides of the side plates and 'are secured rthereto byv horizontal bolts, 7, thus providing a substantial brace or tie-from one side plate to the other. In cases where-a f1' bar is used as the tension member, the end flanges, 1d, may be formed upon the web, and the flanges of the bar may be turned downwardly toorm-langes, l,adapted to abut against the inner sides of the side plates.

' The ridge pole, 4, and purlins, 5, are secured to the compressionmembers by bolts, 4, ,and 5", respectively, and they may alsof be additionally secured in position byv interposed distance blocks or .abutments Patented Nov. 5, 1907,. v

of wood, boltedjor otherwise secured to the tops of the compression members. As shown in Figs. 3, 4, and

6, the ridge pole and purlins are set'between pairs of angles, 8, which are suitably secured to. the compression members, and form pockets for the ridge pole and purlins. It will be obvious that when the angles are employed, theyy perform the same function as abutments as the wooden distance blocks, and therefore that the latter would not be used.`

vA roof carline constructed substantially as above described may-be readily and inexpensively manufactured, and is of substantial strength and stiffness while comparatively light. The facilities which it affords for the support of the superposed roof structure and Ior the transverse bracing of the side plates will be apparent to those rfamiliar with car construction.

I claim as 'my invention and desire to secure by .Letters Patent:

connected thereto adjacent to their ends. which are |f' adapted to t in recesses in the side plates of a car frame, the tension member having lateral anges adapted to lie longitudinally of and abut against the outer sides of the side plates.

V2. A metal roof carline 'comprising two compression members of angle section, bent 'downwardly from their middleportions towards their ends, a tension member or tie interposed between the compression members and conwith the side plates of a car frame having recesses to receive the carline ends, the tension member having lateral flanges adapted to lie longitudinally of and abut against the outer sides ot the side plates.
